National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Study of residual nuclide yields in 1.0 GeV proton irradiated (208)Pb and 2.6 GeV proton irradiated (NAT)W thin targets.

Publication Date	2000
Personal Author	Tiarenko, Y.

Abstract	Some 113 residual product nuclide yields in a 1.0 GeV proton-irradiated thin monoisotopic 208Pb sample and some 107 residual product nuclide yields in a 2.6 GeV proton-irradiated (nat)W sample have been measured and simulated by different codes. The irradiations were made using proton beams extracted from the ITEP synchrotrons. The nuclide yields were y-spectrometered directly using a high-resolution Ge-detector. The y-spectra were processed by the GENIE2000 code. The ITEP-developed SIGMA code was used together with the PCNUDAT nuclear decay database to identify the y-lines and to determine the cross-sections. The 27Al(p,x)22Na reaction was used to monitor the proton flux. The measured yields are compared with their values simulated by the LAHET, CEM95, HETC, CASCADE, IN-JCL, YIELDX, and other codes. Estimates of the mean deviation factor are used to demonstrate the predictive power of the codes. The results obtained maybe of interest in studying the hybrid Accelerator-Driven System (ADS) facilities.
